KURT 'I'. POTTHOFF, OF BROOKLYN, NEW YORK, ASSIGNOR 0F ONE-HALF T. POTTHOFF, OF BROOKLYN, NEW YORK BOOTH Application le. July 19,

f booth floor of simple inexpensive construction acting to position and hold the vertical members of the booth in proper relation and at the same time fitting the booth to the floor pavement or other support on which it rests.

A further object of the invention is to provide the booth floor in the form of a single integral metal sheet shaped and stamped to cooperate with the remainder of the booth as a plurality of structural members, and at the same time of simple regular contour easily galvanized or plated to provide it with a strong unbroken protective coating, rendering it rustproof in service.

In the accompanying drawings illustrating the invention Fig. 1 is a plan view of the floor member,

Fig. 2 is a side view thereof,

Fig. 3 is a front view thereof, and

Fig. 4 is a sectional view on large scale taken on the line 4-4 of Fig. 1 and looking in the direction of the arrows.

In the embodiment of theinvention shown in the drawings the floor is formed of a single piece of plate steel, #1.0 U. S. standard gauge, cut from stock to provide the body member 6, side flanges 7 and rear flange 8, which flanges are drilled as indicated at 9 and bent upward substantially at right angles to the plane of the body portion 6 so as to form in eect the side angle irons stiffening the side portions from front to back and the rear angle iron stiffening the back portion from side to side.

The front edge of the floor has a out away portion 10 and drill holes 11 for fitting an attachment of a sill member shown in Fig. 1 and designated by the numeral 12. The structural side and back members of the booth indicated in broken lines in Figs. 2 and 3 and designated by the numeral 13 are fitted within the flanges 7 and 8 and bolted thereto through the bolt holes 9, and a sheet of flooring preferably of rubber, designated 15, is laid within the sill and structural side and back members.

Corner feet or bosses 16 are stamped down- 'roy GERARD FLOOR 1930. Serial No. 469,070.

ward from the plane of the sheet to a distance slightly greater than lthe thickness of said sheet and -serve as points of support for the booth resting on the flooring or pavement on which the booth is set, while a similar central boss 17 is provided as a support for the center of the floor. Intermediate the front bosses 16 elongated supporting bosses 18 are provided along the front edge and are preferably of less depth than the corner bosses so as not to interfere in any way with the contact between these corner bosses and the supporting surface for the booth.

The entire base or floor member being thus provided in simple form of an integral metal sheet of substantially uniform thickness permits the base, if not already treated, to be rustproofed, for instance by electro-galvanizing to` surface it with a coating of Zinc.. substantially uniform layer of protective deposit may thus readily form on the base over` the outer surfaces, or the entire surface thereof, so that there are no points or areas of weakness in the coating, and the entire bottom or floor is thus provided as a single integral completely coated structure.

Due to the gage of the sheet there is a slight flexibility of this base or floor member permitting it to accommodate itself to irregularities in the booth structure and the pavement 'of the floor structures upon which it is supported. The fastening flanges 7 and 8 also serve as longitudinal and transverse stiffening members, and may be terminated as shown short of the corners. The integral construction of the base or iioor member also makes it durable in service, and there are no joints or fasteners to corrode or loosen, and at the same time the simple formation of the body plate and flanges gives the booth structure a simple neat appearance.

I claim:

In a telephone booth structure a base or floor providing the entire bottom portion of the booth and comprising portion formed with integral downwardly directed bosses acting to support the entire booth in spaced relation to the floor or other support and adapted to receive and retain a iiooring material, side flanges extending upa horizontal body 1 Ward for connection to the vertical sides of the booth, a. rear flange extending upward and adapted to be fastened to the rear of the booth, said side and rear anges giving an angle bail shape to the side and back edges, the front edge of the base receiving and supporting a sill member, said entire base or floor being formed of a single integral sheet out and bent to provide the various cooperating parts in one unit having all of its surfaces completely accessible for rustproong.
